The recent updates focus on enhancing Kubernetes cluster tools, including Grafana, OpenTelemetry Collector, and Prometheus. Changes involve disabling unused features, refining data source URLs, and updating node selectors in Grafana. For OpenTelemetry, adjustments were made to the image repository and Loki exporter endpoint. Prometheus configurations were extensively updated to improve cluster monitoring capabilities.

🐇💻🌟
In the garden of code, under the moon's glow,
A little rabbit tweaks the flow.
Grafana's charts, Prometheus' might,
Together they bring the data to light.
Hop, skip, a dash of code,
In Kubernetes, watch the magic unfold! 🌟🐇💻

molecules/cluster-resources/config/externals/opentelemetry-collector/values.yaml (3)
`6-6`: Ensure the new image repository `otel/opentelemetry-collector-contrib` is compatible with the Raspberry Pi architecture. --- `21-21`: Updated Loki exporter endpoint to `http://loki-stack.homelab.svc.cluster.local:3100/loki/api/v1/push`. Confirm that the new URL is reachable from within the cluster. --- `22-24`: The default labels for the Loki exporter have been modified. Ensure that these changes align with the intended labeling strategy for logs.molecules/cluster-resources/config/externals/grafana/values.yaml (4)
`101-101`: The `testFramework` feature has been disabled. Confirm that this is intentional and that no automated tests rely on this feature.Verification successful
--- The search for references to `testFramework` in the repository indicates that it is only mentioned in the `grafana/values.yaml` file where it has been disabled. This suggests that the disabling of the `testFramework` feature is an isolated change and does not impact other parts of the codebase. Therefore, it appears that the review comment concern has been addressed properly. - `molecules/cluster-resources/config/externals/grafana/values.yaml`: Only reference to `testFramework`, confirming its isolation.--- `529-529`: Updated the Loki datasource URL to `http://loki-stack:3100`. Verify that this URL correctly points to the Loki service within the cluster. --- `258-259`: Node selector `kubernetes.io/hostname: pi` added to ensure Grafana runs on the intended Raspberry Pi node. Confirm that this label is correctly assigned to the target node. --- `1107-1108`: Node selector `kubernetes.io/hostname: pi` added to the image renderer to ensure it runs on the intended Raspberry Pi node. Confirm that this label is correctly assigned to the target node.Scripts Executed
The following scripts were executed for the analysis: --- Script: ```shell #!/bin/bash # Search for any references to the testFramework in the repository to ensure it's not required elsewhere. rg 'testFramework' --files-with-matches ``` Length of output: 104molecules/cluster-resources/config/externals/prometheus/values.yaml (4)
`395-395`: Ensure the node selector label matches the intended deployment environment. --- `62-66`: Confirm the Prometheus config reloader image version is compatible with the Raspberry Pi architecture. --- `166-171`: Check if the Prometheus server image tag is specified and appropriate for the deployment. Consider specifying a tag for the Prometheus server image to ensure a stable and predictable deployment environment. --- `804-804`: Review the security implications of disabling TLS certificate verification. Disabling TLS certificate verification (`insecure_skip_verify: true`) can expose the deployment to man-in-the-middle attacks. Ensure this is only used in a controlled environment and consider enabling verification in production.
